Most BMW models now feature Condition Based Servicing (CBS), which replaces the older inspection-style service system. Condition Based Servicing works by using the vehicle sensors to constantly monitor parts that are subjected to wear. When the service component is no longer working at full efficiency, it will alert the driver by activating the service symbol on the dashboard.
The driver is then able to access this information using the on-board computer management system. David Paul of Warrington can assess this information in order to provide suitable recommendations and costings.
